Implementation science (IS) aims to systematically analyze and address the real-world gaps from evidence to practice and the influencing factors of the context. It is necessary to carry out qualitative research to gather relevant implementation outcomes. Nevertheless, traditional qualitative analysis has issues such as consuming a great deal of time and energy, and it is unable to promptly provide the crucial data required for implementation science research. The Rapid Qualitative Analysis (RQA) method, through semi-structured interviews and the adoption of techniques such as immediate data condensation and matrix analysis, can effectively shorten the cycle of qualitative data collection and data processing. RQA can promptly identify social determinants of health such as structural barriers, facilitators, and the behavioral characteristics of target groups. It provides a real-time basis for public health decision-making, the interpretation of complex social phenomena, and the process and effectiveness evaluation of research projects. Although RQA is difficult to conduct in-depth theoretical analysis based on grounded theory, its efficiency and flexibility make it the preferred tool for large-scale and time-sensitive research. Thus, it has been widely applied in implementation science research. This paper sorts out the core concepts and commonly used technical methods of RQA, as well as the differences between RQA and traditional qualitative analysis. It also explores the applications of RQA in intervention optimization, process evaluation, and implementation outcome evaluation. By integrating specific cases, this paper clarifies its application value in the field of implementation science. In the future, it is advisable to explore the integration of RQA with technologies such as artificial intelligence and big data, in order to bridge the gap between the transformation of scientific research achievements into practice. Under circumstances of limited resources or tight time constraints, RQA can be used to efficiently conduct implementation science research, providing convenient and scientific methodological and technical support for accelerating evidence-based practice.

Objective:To investigate the application value of D-dimer (D-D) as the primary indicator, combined with NT-proBNP and neutrophil percentage in the differential diagnosis of acute aortic dissection (AAD), pulmonary embolism (PE), and acute myocardial infarction (AMI).Methods:A retrospective case-control study was conducted, including 764 patients with acute chest pain who presented to the Emergency Department of Beijing Fuwai Hospital from March 1st, 2024, to February 28th, 2025. Patients were clinically diagnosed with AAD (299 cases) and other acute chest pain conditions (AMI 425 cases, PE 40 cases). The AAD group had the age of 56.00 (45.00, 64.00) years old with 226 males (75.59%); the AMI group had a median the age of 65.00 (55.00, 70.00) years with 339 males (79.76%); and the PE group had the age of 70.00 (59.75, 74.00) years with 15 males (37.50%). Baseline clinical data were collected and compared among the three groups, including general parameters such as heart rate, systolic blood pressure, and diastolic blood pressure. Laboratory parameters included N-terminal pro-brain natriuretic peptide (NT-proBNP), prothrombin time (PT), activated partial thromboplastin time (APTT), D-D, cardiac troponin I (cTnI), myoglobin, creatine kinase-MB (CK-MB), white blood cell count, neutrophil percentage, lymphocyte percentage, platelet count, and mean platelet volume (MPV). Comparisons between groups were performed using the Kruskal-Wallis rank-sum test and χ2 test. Independent discriminatory factors were identified through multivariate logistic regression analysis, and the diagnostic performance of individual indicators and combined models were analyzed using receiver operating characteristic (ROC) curves.Results:The D-D level in the AAD group [3.93 (1.48, 19.59) μg/ml] was significantly higher than that in the AMI group [0.26 (0.14, 0.56) μg/ml] and PE group [2.13 (0.84, 6.13) μg/ml] ( F=200.12, P<0.001). Multivariate analysis showed that D-D, NT-proBNP, neutrophil percentage, and lymphocyte percentage were all independent factors for differentiating AAD from AMI. NT-proBNP, total white blood cell count, neutrophil percentage, and lymphocyte percentage were independent predictors for differentiating AAD from PE. ROC analysis showed that D-D had an area under the curve (AUC) of 0.93 (95% CI 0.91-0.95) for differentiating AAD from AMI, with a sensitivity of 81.6% and specificity of 92.9%. In the differential diagnosis between AAD and PE, the model combining D-dimer, NT-proBNP, and neutrophil percentage had an AUC of 0.86 (95% CI 0.80-0.91), with a sensitivity of 85.0% and a specificity of 72.5%. Conclusion:D-D has significant value in the differential diagnosis of AAD from AMI and PE, with particularly good individual diagnostic performance for differentiating AAD from AMI. Combining NT-proBNP and neutrophil percentage can significantly improve differential diagnostic performance.

Objective:To explore the the application and outcomes of microscopic vocal cord shortening with retrodisplacement of anterior commissure in voice feminization surgery.Methods:We conducted a retrospective analysis of 296 patients(including 3 cases of pseudohermaphroditism and 293 transgender women)who underwent this procedure at the Voice Center of Nanjing Tongren Hospital of Otolaryngology-Head and Neck Surgery between November 2014 and August 2023. The patients, aged 18-50 years (mean age of 28.3±14.5) underwent feminizing laryngoplasty via transoral microsurgery, involving resection of the superficial lamina propria of the anterior vocal cords and subglottic tissues of the anterior commissure, followed by vocal ligament plication to achieve vocal cords shortening and anterior commissure retrodisplacement. Patients adhered to a1-month voice rest postoperatively and subsequently underwent speech rehabilitation training. Subjective/objective voice analyses, aerodynamic evaluations, and stroboscopic examinations were performed at 3, 6, and 12 months postoperatively to assess the effectiveness of voice feminization.Results:All surgeries were performed successfully and 94.3% (279/296) of the patients reported satisfaction at the end of the one-year follow-up. For effective cases, fundamental frequency (F 0) increased by 57.42±16.72 Hz compared to baseline. Postoperative acoustic/aerodynamic parameters and stroboscopic findings of vocal cord mucosal wave motion remained within normal ranges. These results indicated that this voice feminization surgery combined with postoperative pronunciation training achieved natural and feminine vocal characteristics. Conclusion:The combination of vocal cord shortening and anterior commissure retrodisplacement, along with postoperative pronunciation training, represents an effective surgical strategy for achieving a natural feminine voice.
